Abstract
A cannulated screw having a resilient balloon structure capable of supporting compressive and cyclic loads. The balloon provides an artificial disc prosthesis by use of the balloon that mimics the properties of the natural disc by maintaining the intervertebral disc space through a full range of natural motion, absorbing shocks and permitting a natural range of motion.
